5 precision-engineered series — from drop-in replacement to explosion-proof petrochemical environments. Compliant with QCVN 26:2025 noise limits and the 2024 Electricity Law energy requirements.
In Vietnam's industrial cooling, long-term reliability dictates the true total cost of ownership.
Mechanism: Replacing metal shells with electrochemically inert FRP materials fundamentally cuts off the corrosion path at the material level.
Result: Ensures the tower body maintains structural integrity even in highly humid, high-salinity coastal environments, drastically reducing the risks of rusting, leakage, and unplanned downtime.
Mechanism: Utilizing gravity water troughs instead of high-pressure nozzles in crossflow series reduces system head loss by 4-6 kPa through pressure-free flow.
Result: Directly relieves the operational burden on water pumps, translating into quantifiable long-term savings in annual electricity and maintenance costs.
Mechanism: Harnessing residual head pressure from the piping network to drive the fan instead of an electric motor, reducing fan operational power consumption to absolute zero.
Result: Zero electrical components on the tower top eliminates electrical spark sources, making it naturally suited for compliance in explosion-proof zones like petrochemicals.
Covering Crossflow, Counterflow, Closed-Circuit & Turbine Drives
For factories where the old round cooling tower has reached the end of its lifespan and must be replaced within the shortest possible downtime window. The core value is compatibility and speed.
Suitable for noise-sensitive areas, and industrial or commercial projects in Vietnam that need to reduce pump energy consumption while improving the convenience of daily maintenance.
Suitable for manufacturing scenarios where industrial park space is locked tight, and downstream equipment has stricter requirements for the stability of outlet water temperature.
Suitable for petrochemical, chemical, and steel projects focusing on explosion-proof compliance and energy-saving retrofits, but requires confirmation of system residual pressure.
Suitable for induction furnaces, injection molding machines, semiconductors, and other water-quality-sensitive equipment. Focuses on long-term protection rather than just single heat exchange.
